THOMAS S. HOWARTH, OF LA. SALLE, ILLINOIS.

VALVE-LIE TER WASHER.

Application filed April 14, 1924. Serial No. 706,461.

To all whom it may concern:

Be it known that I, THOMAS S. Howan'rrr, of the city of La Salle, county of La Salle, and State of Illinois, have invented certain new and useful Improvements in Valve-Lift er Vashers, of which the following is a specification.

My invention relates to valve lifter washers for gasoline motors and the like and has for its object the production of such a washer that greatly facilitates the work of grinding valves and removing the valves as well as replacing the valves and the valve parts such as the springs, etc, and yet at the same time is very simple and inexpensive.

I accomplish these objects by the means shown in the accompanying drawings in which- Fig. 1 shows a cross-sectional view of the valve chamber 011 a gasoline motor showing the washer used in combination with the valve lifter.

Fig. 2 is an enlarged cross-sectional view of the valve showing my washer in cross section along a line AB on Figure 3.

Fig. 3 is a top view of the washer.

In the drawing 1 represents the block or frame of the gasoline motor. 2 is the usual valve chamber having the valve 3 with its stem 5 slidably mounted in an aperture 4: through the lower part of the valve chamber, said stem 5 projecting beyond the block making a space for the usual spring 6, and my washer 7 which is retained in position by means of a pin 8 pass ing through the stem 5 as shown. My wash.- er is shown preferably made up out of a single piece of material and is cup shaped as shown (see Fig. 3) having the flat portion 15 an outer rim 16 and the diametrically opposite lugs 10 which are preferably formed integral with rim l6 and are suitably shaped as shown in cross section in Fig. 2 so that the prongs 9 of valve lifter 1.1 register with same. V'Vasher 7 further has an aperture shown through which valve stem 5 passes and which aperture has a flaring up portion 14: as shown which enables an operator to readily position my washer on the valve stem and on the coiled spring as shown in Fig. 2. Valve lifter 11 is suspended by means of chaln 12 whose other end is usually fastened to some convenient point on the motor and is actuated by means of the handle 13.

From the above description it is evident that I have produced a valve lifter washer which is very convenient and makes the work of removing and replacing and grinding of valves a very simple and easy operation over the use of the former valve lifter and at the same time it is comparatively inexpensive to produce.

It will be understood of course that while I have here shown one of the forms of my washer I do not wish to limit myself to the exact form shown but wish to have it taken in a sense illustrative of any and all forms that come fairly within the scope of my claims.

I claim 1. In a valve lifter washer, a disk having an aperture, a flanged portion integral with said disk, and a plurality of projections extending from said flanged portion.

2. In a valve lifter washer, a disk having a flared aperture, a flanged portion integral with'said disk, and a plurality of projec tions extending from but integral with. said flanged portion.

3. In a valve lifter washer, a cup shaped member having a flared aperture and a plurality of projections formed integral with said cup shaped member.

4. In a valve lifter washer, a cup shaped member having a flared aperture and a plurality of suitably formed projections extending from but formed integral with said cup shaped member.

5. In a valve lifter washer, a cup shaped member having a flared aperture and a plurality of suitably formed projections extending from but formed integral with said cup shaped member, in combination with means for moving said washer.

6. In a valve lifter washer, a cup shaped member having a flared aperture and a plurality of suitably formed projections extending from but formed integral with said cup shaped member, in combination with means for moving said washer, said means comprising a lever having a forked end.

THOMAS S. HOIVARTH.
